The Breitling Navitimer: A Pilot's Computer on the Wrist
Long before cockpit computers, pilots carried slide rules. In 1952 Breitling put one on the wrist. The Navitimer combined a chronograph with a rotating circular slide rule, letting pilots calculate speed, distance, fuel consumption and rates of climb. It became one of the great aviation watches, and it is still made today.
The slide rule
The Navitimer's bezel turns a logarithmic scale against a fixed scale on the dial. By aligning numbers, a pilot can multiply, divide and convert units. It looks complex, and it is, which is part of its appeal: a dense, purposeful dial that rewards learning.
Key moments
- 1952: the Navitimer is introduced, closely associated with the Aircraft Owners and Pilots Association, whose winged emblem appeared on many dials.
- 1962: astronaut Scott Carpenter wears a Navitimer adapted with a 24-hour dial in orbit; the model becomes the Cosmonaute.
- 1969: automatic chronograph versions follow.
- Modern era: the Navitimer continues in many sizes and calibres, including Breitling's in-house movements.
What collectors look for
- Vintage manual-wind Navitimers from the 1950s and 1960s, with original dials.
- The Cosmonaute with its 24-hour display.
- Modern classics such as the Navitimer 806 re-editions, faithful to the originals.
What to check
- Bezel: it should turn smoothly; the beads around the edge are fragile on vintage pieces.
- Dial: crowded printing makes refinishing easy to spot when it is poorly done.
- Chronograph: start, stop and reset should be clean.
- Papers and service: Breitling chronographs need regular servicing.
Questions collectors ask
Do I need to use the slide rule?
No, though many owners enjoy learning it. It is part of the watch's character.
Is a modern Navitimer collectible?
Yes, especially limited and heritage editions, though vintage pieces carry the history.
Why are Breitlings popular in Japan?
Japanese collectors have long valued tool watches with history, and many Navitimers have been carefully kept with papers.
